SPECTACLES.

SPECIFICATION forming part of Letters Patent o. 625,083, dated May 16,1899.

Application filed January 23, 1899. Serial No. 703,105. (No model.)

T0 all whom it may concern.-

Be it known that I, WILLIAM E. BELT, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois,

have invented certain new and useful Im-` provements in Spectacles, ofwhich the following is a specification.

My invention has for its object an improved frame for securing the lensin spectacles and providing a temple-joint for same. It has heretoforebeen customary to construct the joint-pieces integral with the bows andconnect them with screws, rivets, or the like.

The primary object of my invention is to provide a frame which shallconsist of as few parts as possible and be so assembled as to do awayentirely with screws, rivets, soldering, &;c., and yet have a framewhich shall be eX- ceedingly simple in construction, cheap and easy tomanufacture, edective, and practically impossible to get out of order.To accomplish this end, I employ a single strip of wire to form the rim,and the bow is bent to form its own fastening at the temple-joint, andother novel features which will be hereinafter more fully explained.

In the drawingsFigure l represen ts a spectacle-frame,showing myimproved form of rim and temple-joint. Fig. 2 represents an edge Viewshowing one of the bows open and the other closed. Fig. 3 is an enlargeddetail of the temple-joint. Fig. 4 is a View taken on the line 2 2 ofFig. 1. Fig. 5 represents a portion of the rim containing the lensbroken away. Fig. 6 is an enlarged detail of the clamp used on the rim.Fig. 7 is a plan view of a section, showing a modified form.

In carrying out the invention, A represents the ends of the wireemployed to form the entire rim. It is first bent to conform to theupper half of the lens, then outwardly, then at right angles, and backagain to form an ear or projection A', then back to form the lower halfof the lens,then gradually curved to form the nose-piece B andcontinuing around the other lens in the ,same manner as the first, and,finally, ending on the opposite side of the nose-piece, where it issecurely fastened by means of a small clamp IJ.

C is the wire, which forms the bows and which also is bent to form thetemple-joint.

A loop C' is bent in one end of this wire C, and this is passed throughthe projection A' from the outside and bent once around the wire,forming the projection A. The wire is then secured by winding tightlyaround the bow close to the temple-joint.

b2 is a clamp which is bent around the projection A to form an abutmentfor the loop C'. This serves to keep the bows adjusted to the desiredposition when open and prevents the loop C from coming into contact withthe edge of the lens.

D, Fig. 7, represents another form of-my improved spectacle-frame, whichis more simple and equally as effective as the one above described. Inthis I form the entire rim of a single piece of wire, and instead ofproviding the clamps as shown at Z)- 192 in Fig. 1 in bending the wireto form the projection at the outer end of the lens I am able to use thesame wire by bending it to form a small loop d within the projection A',which will serve as effectually as an abutment for the templejoint loopC as the clamp b2. In this form of rim I am enabled todo away with theclamps b also by securing the ends of the eyewire A simply by tightlycoiling them around that portion ofl the wire between the lower hal ofthe lens and the nose-piece, as shown at c It will thus be seen that Ihave provided a spectacle-frame which is exceedingly simple inconstruction and eective in application and have dispensed with allscrew-fastenin gs,

rivets, &c., and making it practically impossible for the frame ortemple-joint to get out of order. I do not desire to be limited to thespecific construction shown in the drawings, as the details thereofmight be changed without departing from the spirit of my invention,which consists, essentially, in providing 'a spectacle-frame composed ofa single piece of wire bent in conjunction with the pieces of wireforming the bows to form the templejoint. v

Having thus described my invention, what I desire to secure by LettersPatent is-- l. Aspectacle-frame having the entire rim loop in one end ofeach of the bows bent Io formed of a single piece of Wire, projectingaround the Wire of said projecting loops, and loops in each end of saidrim, an elongated forming a hinge, substantially as described. loop onone end of each bow bent around the In testimony whereof l hereunto signthis 5 Wire of said proj eeting loop to form the hinge specification inthe presence of two Witnesses. or temple-joint, substantially asdescribed. WILLIAM E. BELT.

2. In spectacles, the combination of a rim Witnesses: having projectingloops at each end thereof, HERBERT A. KING, with a temple-jointconsisting of an elongated J. S. MCGREGOR.
